Marble

Marble is a metamorphic rock consisting of carbonate minerals that recrystallize under the influence of heat, pressure and aqueous solutions, most commonly calcite (CaCO3) or dolomite (CaMg (CO3)2) and has a crystalline texture of varying thickness. Marble is typically not foliated (layered), although there are exceptions.

In geology, the term marble refers to metamorphosed limestone, but its use in stone-masonry more broadly encompasses unmetamorphosed limestone. Marble is commonly used for sculpture and as a building material.
